INSTRUMENT ASSISTED ABDOMINAL ACCESS
First Claim
1. A method for endoluminally accessing a space within a patient body, comprising:
- advancing an elongate body in a flexible state through a natural orifice into the patient body;
creating an opening through a tissue wall of a body lumen for accessing the space within the patient body;
advancing a tissue engagement device upon a flexible elongate member through the opening into the space;
anchoring the tissue engagement device into a tissue wall outside the opening; and
passing at least a distal portion of the elongate body over the flexible elongate member and through the opening.

Abstract
Instrument assisted abdominal access methods and apparatus are described herein. A shape-lockable elongate body can be advanced endoluminally in a flexible state into the stomach, where an opening is created through the stomach wall. The opening can be created endoluminally or by incising instruments placed through the abdominal wall. The elongate body can be transitioned to a rigid state prior to, during, or after advancement into the patient and is passed through the opening into the peritoneal cavity. To assist in the passage of the elongate body, a helical tissue engager can be advanced into the peritoneal cavity and temporarily anchored into a tissue wall. By pulling the helical tissue engager proximally and pushing the elongate body over a flexible length of the engager, the elongate body can be brought into the peritoneal cavity
